WINDING- SPINDLE.

SPECIFICATION forming part of Letters Patent No. 408,396, dated August6, 1889. Application filed February 7, 1889 Serial No. 299,027- (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH E. TYNAN, of Paterson, in the county ofPassaic and State of New Jersey, have invented a new and use fulImprovement in WVinding-Spindles, of which the following is aspecification, reference being had to the accompanying drawings.

My improvement relates more especially to spindles for carrying bobbinsonto which silk is wound for the purpose of being afterward spun ortwisted. Such bobbins, after having the silk wound upon them,'areremoved from said spindles and placed upon the spinningspindles, by therotation of which the silk is spun ortwisted as it is drawn oif from theends of the bobbins. These bobbins have within them a conical bearingwhich fits to a taper portion of the spinning-spindles. Thewinding-spindles are provided with frictionrollers by which to drivethem and with springs by which to secure the bobbins upon them. Thesesprings as heretofore applied have come into frictional contact with theconical bearing in the bobbins, often so damaging such bearing as tomake the bobbin unfit for use by reason of its bearing being untrue.

The object of my invention is to provide for supporting the bobbin uponthe winding-spindle in such manner that it may be held concentric withthe spindle throughout its whole length, and that it may be securedthereon by the springs without the springs coming in contact with theconical bearing and producing the injury hereinabove referred to.

I will now proceed to describe my invention with reference to thedrawings, and afterward point out its novelty in the claim.

Figures 1 and 2 are outside longitudinal views, taken at right angles toeach other, of a winding-spindle embodying my invention. Fig. 3 is alongitudinal View of the spindle corresponding with Fig. 1 and havingits head and the friction-roller, which forms a part thereof, insection. Fig. 4 is a view corresponding with Fig. 3, and alsorepresenting a bobbin in section upon the spindle. Fig. 5 is an end viewof the spindle.

Similar letters of reference designate corresponding parts in all thefigures.

of the usual form.

B and O designate the head, the portion B of which resembles thefriction-roller commonly provided on such spindles for the purtion C ofwhich constitutes a cylindrical prolongation of a reduced size, thepurpose of this prolongation being to enter and fit easily within oneend of the bobbin D, which is bored larger than is common in suchbobbins for the purpose of receiving said prolongation. The said headhas in it radial slots Z) to receive portions of the spring E, which isemployed to secure the bobbin to the spindle.

The spring E, which is of substantially the same form as that commonlyused in such spindles,is composedof a pieceof wirewhich is fastenedatthe center of its length in the spindle, and which is turned back inthe form of two horns, which press against the interior of that portion(Z of the bore 6 of the bobbin which fits the prolongation O. The saidspring differs only in any material manner from those commonly employedin its being so arranged in the spindle that it will not enter theconical bearing a, provided in the bobbin to fit the spinning-spindle.The said spring has free play within the slots b.

The conical bearing a inthe bobbin is like that commonly provided insuch bobbins, ex cept that it is or may be shorter, and the spindle fitseasily within the small end of it, so as to center the bobbin upon it.By this construction of the spindle and spindle-head and this mode ofapplying the spring not only is the conical bearing a in the bobbinpreserved and the bobbin rendered more durable, but the bobbin is morefirmly centered upon the spindle throughout its whole length, owing toits fitting the prolongation C of the head, and the springs E have abetter hold upon the bobbin by means of their pressing against itsinterior at a greater distance from the center. The springs are,moreover, sustained against torsion by being received within theslots 1) of the head. It may also be remarked that another reason whythe springs thus applied have a better hold is that in bobbins ascommonly made the heads are of harder wood than pose of driving them forwinding, and the por- A is the spindle proper, which is or may befriction roller for driving the same and another portion of which isconcentric with but of less diameter than the said roller and islongitudinally slotted, and a spring which is secured to the spindle,and a part of which lies within the said slot, substantially as and forthe purpose herein set forth.
